Fixed bug 2464 ("open each item in a new window" sometimes
	reuses an existing window)

	* libnautilus-extensions/nautilus-global-preferences.c:
	(global_preferences_register): Changed preferences text to
	say "separate window" rather than "new window"


	Fixed bug 2752 (double-clicking Help item causes "sidebar view
	failed" message)

	Fixed bug 5040 (only one dead view name gets saved for a window)

	This was a tangled mess of issues, including: (1) the dialog
	code was incorrectly guessing "sidebar panel" when a content
	view failed in some cases (fixed); (2) view frame lifetime
	issues found while working on (1) (fixed); (3) the state machine
	can fail if asked to load the same location twice very quickly
	(written up as bug 5197); (4) the Help sidebar panel asks to
	load the same location multiple times on a double-click (fixed);
	(5) Mozilla sometimes fails to load just after it has quit
	(written up as bug 5199).

	* components/help/hyperbola-nav-tree.c:
	(hyperbola_navigation_tree_new): Connect to destroy signal of
	ctree widget.
	(set_pending_location): New helper function to remember the
	location for which this component just initiated a load.
	(hyperbola_navigation_tree_load_location): Set pending location
	to NULL now that there's a new real location.
	(hyperbola_navigation_tree_select_row): Don't try to start a
	new load of the pending location; set the pending location when
	we do start a new load.
	(hyperbola_navigation_tree_destroy): free pending location.

	* src/nautilus-view-frame.c:
	(nautilus_view_frame_initialize_class),
	(nautilus_view_frame_destroy), (nautilus_view_frame_finalize):
	Don't destroy details fields until finalize, so view_frame objects
	with extra refs can survive between destroy & finalize.

	* src/nautilus-window-manage-views.c:
	(view_frame_info_new), (view_frame_info_free): New helper
	functions for dealing with the label & sidebar-panel-ness
	of a view frame.
	(set_view_frame_info): New helper function for storing
	the label & sidebar-panel-ness of a view frame in object
	data in the view frame.
	(view_frame_is_sidebar_panel), (view_frame_get_label):
	New helper functions for retrieving info stored in object
	data in the view frame.
	(report_content_view_failure_to_user_internal),
	(report_current_content_view_failure_to_user),
	(report_nascent_content_view_failure_to_user),
	(report_sidebar_panel_failure_to_user): Reworked the functions
	that put up the "view failed" dialog to take a NautilusViewFrame
	and to distinguish the existing-content-view from content-view-
	that's-being-created cases.
	(disconnect_view_and_destroy), (disconnect_destroy_unref_view):
	New helper functions for cleanly forgetting about a view.
	(handle_view_failure): Use object data to distinguish content views
	from sidebar panels so we'll always get the right failure dialog.
	(update_state), (change_state): Get rid of dead_view_name mechanism;
	the name is now stored in the view frame in all cases.
	(load_content_view), (free_location_change),
	(nautilus_window_begin_location_change),
	(nautilus_window_set_sidebar_panels): Jigger around the reffing &
	sinking of NautilusViewFrames to fix leaks and uncancelled-callback
	issues.

	* src/nautilus-window-private.h: remove obsolete dead_view_name
	field.
	* src/nautilus-window.c: (nautilus_window_destroy):
	Don't free now-non-existent dead_view_name field.
